Before installing .NET, you will need to register the Microsoft key, register the product repository, and install required dependencies. This only needs to be done once per machine. Refer to Setting up Linux for .NET Core for the requirements.
The commands listed below do not specifically include package managers to help with readability. Here are the package managers typically used by the Distros on which .NET Core is supported.
| Distro | Package Manager |
|---|---|
| CentOS, Oracle | yum |
| Debian, Ubuntu | apt-get |
| Fedora | dnf |
| OpenSUSE, SLES | zypper |
To develop applications using the .NET Core SDK, run the following command. The .NET Core runtime and ASP.NET Core runtime are included.
sudo [package manager] update or refresh
sudo [package manager] install dotnet-sdk-2.1If you only need to run existing applications, run the following command. The .NET Core runtime and ASP.NET Core runtime are included.
sudo [package manager] update or refresh
sudo [package manager] install aspnetcore-runtime-2.1Installing from the packages detailed above is recommended or you can install from binary archive, if that better suits your needs. When using binary archives to install, the contents must be extracted to a user location such as $HOME/dotnet, a symbolic link created for dotnet and a few dependencies installed. Dependency requirements can be seen in the Linux System Prerequisites document.
mkdir -p $HOME/dotnet && tar zxf dotnet.tar.gz -C $HOME/dotnet
export PATH=$PATH:$HOME/dotnetIf only the .NET Core Runtime is needed, install dotnet-runtime-2.1 using your package manager. If you also need ASP.NET Core functionality, installing aspnetcore-runtime-2.1 will install both the ASP Runtime and .NET Core Runtime.
If you are looking to host stand-alone apps on Servers, the following installer can be used on Windows systems.
You can download the Windows Server Hosting installer and run the following command from an Administrator command prompt:
This will install the ASP.NET Core Module for IIS.
